Giardini Poseidon Terme (Ischia)

Giardini Poseidon Terme is a large thermal park on Citara Bay in Forio on the island of Ischia, in the Bay of Naples, Campania, Italy. It is a day trip from Naples rather than a city venue: visitors take a ferry from Molo Beverello or Calata Porta di Massa to Ischia and then a local bus to Forio. The setting is a landscaped garden terraced above the Citara beach, with about 20 thermal pools at different temperatures, a sea beach and Roman-style baths. The ambience is lively and outdoor, with sun, greenery and sea views, closer to a resort than to a hushed spa. Ischia has a long tradition of thermalism based on volcanic mineral waters, and the park's pools use that thermal water at temperatures ranging from cool to very hot, so visitors move between pools as in a circuit. The Roman-style baths and the pools are the headline facilities, and the park also offers treatments including mud and massage, which are the signature services here rather than a formal treatment menu. The park's reputation rests on its size and variety, and treatments are booked separately from the entry ticket. Facilities include the pools, the beach, changing areas, loungers, and food and drink outlets typical of a thermal park. The park is seasonal, roughly April to October, and open daily from 9AM to 7PM, but the 2026 closing date should be confirmed on giardiniposeidon.it. Reported prices for 2026 are about €50 for a full day and about €45 for the afternoon from 1PM to 7PM. Booking norms favour buying tickets online or on arrival, with advance reservation of treatments recommended in high summer. Planning matters because of the ferry and bus transfers: visitors should check return ferry times to avoid missing the last departure to Naples. Swimwear, a towel, flip-flops and sun protection are needed, and the pools should be approached gradually, since the hottest ones can be tiring.
